1 Claim. (Cl. 103-140) This invention appertains to new and useful improvements in dispensing apparatus and more particularly to a motor for delivering iluid in measured quantities.

The principal object of the invention isvto provide a fluid dispensing device which when in operation will permit fluid in measured quantities to pass in a conduit in which the same is installed.

Another important object of the inventionis to provide a device for the purpose of dispensing liuids or substances in xed proportions to the quantity or volume of the fluids which pass through the measuring motor and provide the impetus of its operation.

Another important object of the invention is to provide a measuring device which will deliver revolutions of its shaft in xed and exact proportions of quantity for volume of the iluid passing through the device,

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the motor.

Figure 2 is a vertical longitudinal sectional View through the apparatus.

Figure 3 is a vertical transverse sectional view.

Figure 4 represents a base elevational view of the rotor.

Figure 5 represents a fragmentary circumferential sectional view taken substantially on line 5-5 of Figure 4.

Figure 6 represents an elevational view of one of the panes.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to the stator which consists of the circular wall 6 provided with outstanding circumierentially extending anges 'I which are Wider at the top of the stator than at the bottom. End plates 8-8 are disposed against the iianged sides of the stator wall 6, to complete the stator and bolt members 9 are disposed through the anges 'I and the plates 8 to secure these parts together and complete the stator construction. The stator at its lower portion is provided with an inlet l0 and at an opposite point with the larger outlet I I.

It will be observed that the rotor I2 is eccentrically mounted within the ovate-shaped stator 5, in the manner suggested in Figure 2, while I3 represents the shaft which extends transversely through the stator and on this is secured the said rotor I2.

The peripheral portion of the rotor I2 is provided with short circumferentially extending pockets I4 which merge with transversely extending grooveways I5.

Arcuate shaped vanes or plates I6 are con- 10 structed for disposition in the pockets I4 and each is provided with a cylindrical shoulder portion at one longitudinal edge denoted by numeral I1 for rest in a corresponding grooveway I5. These vanes are free to gravitate and as is clearly 15 shown in Figure 1, a sprocket wheel I8 on one outer end of the shaft I 3 has a drive chain I9, so that when the rotor I2 is driven by this drive means it is rotated counterclockwise, as shown in Figure 2, and as each vane I6 passes over the 20 inlet Il), it begins to gravitate until it reaches the position directly under the shaft I3. From this lowermost position it begins to move back toward the rotor and as it passes over the outlet I I, material between it and the next following vane be- 25, gins to discharge.

While the foregoing specication sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing 30 from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

In a machine of the character described, a ro- 35 tor provided with a plurality of circumferentially spaced peripheral pockets of shallow depth, vanes swingably mounted in said pockets, said pockets being substantially longer than the vanes with the bottoms of the pockets extending beyond the 4 0 free ends of the vanes, the free ends of said vanes being beveled in a direction inwardly toward the inner sides of the vanes, said vanes when in contracted position having the major portions of their inner sides engaging with the bottom of the 45 pockets, said vanes being of such thickness as to cause the outer sides thereof to lie flush with the periphery of the rotor when in contracted position.
